SPECIFICATION forming part of Letters Patent No. 829,251, dated October 2'), 1885.

Application filed February 19, 1885. Serial No. 156,394 (No model.) d

To all whom it may concern:

Be it known that I, JOHN O. ALLEY, of

v Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Vapor-Burners for Stoves, of which the following is a specification.

My invention consists in an improvement in vapor-burners for stoves, hereinafter fully pointed outin the claims.

The drawing is an elevation showing the reservoir-pipe broken off, the supply-pipe,

which carries the burners, one burner in full,

and the pipes for two other burners, with my invention attached.

T represents the usual reservoir-pipe,which carries at its upper end a reservoir for the liquid fuel, elevated above the burners; and U represents a supply-pipe running from the lower end of .pipe '1 and carrying the burners.

E R S represent short pipes rising from'the' supply-pipe U, each of which carries a burner at its upper end, the burner being shown in full on pipe E. i

N represents a cap, secured to the upper end of pipe E, carrying the perforated'cone NV and the combining-tube K.

M Lrepresent hollow arms, which support ized by the heat of the 'ilame,and is burned in the form of vapor. 'As the amount of liquid vaporized depends upon the amount of heat generated by the flame, and is governed to a great extent by the degree of temperature attained by the burner, pipe E, and supplypipe U, it follows that whena stove, especially one having more than one burner, is run hard,

all these parts become quite hot, and a large supply of gas is formed: In such stoves the gas flows from theburner irregularly, causing the flame to j ump" or pulsate. This-diffieulty 0 A has been partially remedied by packing the burner-tube with asbestos or other fibrous substances; but this becomes in time clogged, so

as to'entirely prevent the flow of gas to the burner. My invention obviates this difficulty and does away with the lnecessityfof packing V the buinerpipe. l

0 represents a valve on the'supply-pipe U, having a hand-wheel, D, to'operate it, and to i this valve is fastened a piece of pipe bent into the form of a trap, B, on the end of which is a tight hollow ball, A. When liquid is admi't ted from the reservoir to the supply-pipe U to start the stove, the valve G is. opened,and.v

the liquid flows into the trapB and ball A 5 until it compresses the air in said ball to an extent due to the liquid pressure. The confined air in the ball acts like a cushion, and yields to and compensates for anyirregularities in the gas-pressure, so that the flame is steady 7Q and does not jump. I prefer to use the trap B because it prevents the entrance of vapor into the ball A, as would be the case if the ball were near the burners and no trap were used.

I am aware that it is old to admit hydrocarbon to a globular generating-chamber heated from an initial generator below; for the purpose of converting the fluid in the upper generator into gas before passing to the burner. I am also aware that a gasometer containing Water has been connected by a pipe with the part of a vapor-burner wherethe vapor reaches and is burned, the gasometer being for the purpose of receiving surplus gas from the burning-point, so that the over pressure will not check the flow of the oil to the generator, I. lay no claim to GlhhBPOf said features. My invention differs therefrom, among other things, in attaching to the fluid-supply pipe an airchamber, into which the fluid from the supply-pipe will pass and compress the air therein so that the compressed air will" form an elastic cushion to the pressure of the liquid, so as to equalize the pressure of the latter and compensate for irregularities in the gas-pressure during the operalion of burning the generated gas. This air-eh amber is distinct from 2. In a vapor-burner, the e0.11binati0n,with
